<div>Alan,</div><div>I have not had ann bad effects from WD40 except a clear hose went solid. If the mystery oil does not do thatI am happy. I will do a test.</div><div>Hank</div><div><br></div>

<div>Brian,</div><div>I need the oil for my electric arm motors. Normally I would use WD-40, but the arm uses HP nylon hoses connected a suspension air bag. The hoses will harden up with WD-40 and loose their flexibility.</div><div>Hank</div><div><br clear="none"></div>
